Amphoteric naphthoquinone is a versatile organic compound with the molecular formula C10H6O2, characterized by its amphoteric nature, meaning it can act as both an acid and a base. It is derived from naphthalene, a polycyclic aromatic hydrocarbon, and features a quinone functional group, which endows it with strong oxidizing properties. This chemical is known for its ability to form salts with both acids and bases, and it is widely used in various applications, including as a redox indicator, a dye, and in the synthesis of other compounds. Its amphoteric properties make it a valuable intermediate in the chemical industry, and its unique chemical structure contributes to its diverse reactivity and potential applications.

613-20-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 613-20-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,1 and 3 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 613-20:
(5*6)+(4*1)+(3*3)+(2*2)+(1*0)=47
47 % 10 = 7
So 613-20-7 is a valid CAS Registry Number.

Binuclear molybdenum(V)porphyrins bridged by benzenediolate or naphthalenediolate dianion: Cooperative coordination equilibrium of two molybdenum centers involving electron transfer

Kurihara, Masato,Saito, Ikuko,Matsuda, Yoshihisa

, p. 1109 - 1110 (1996)

The reactions of molybdenumporphyrin and an aromatic diol were studied. A cooperative coordination of two hydroxyl groups to molybdenum centers was confirmed.

Calix(n)arene-quinone interactions: Molecular recognition of 2,6-naphthoquinone by 5,11,17,23,29,35-hexa-tert-butyl-37,38,39,40,41,42-hexahydroxycalix(6)arene

Mohindra Chawla,Srinivas,Meena

, p. 2709 - 2718 (2007/10/02)

UV, IR and NMR spectral analyses reveal that 2,6-naphthoquinone forms a 1:1 host-guest type of complex with 5,11,17,23,29,35-hexa-tert-butyl-37,38,39,40,41,42-hexahydroxycalix(6)arene while 1,4-naphthoquinone does not do so at low concentrations (1 × 10s

Molecular recognition of 2,6-naphthoquinone by 5,11,17,23,29,35-hexa-tert-butyl-37,38,39,40,41,42-hexahydroxycalix(6)arene

Chawla, H. Mohindra,Srinivas, K.

, p. 230 - 233 (2007/10/02)

UV, IR and 1H NMR spectral analyses of host-guest complexation of 2,6-naphthoquinone (3) and 5,11,17,23,29,35-hexa-tert-butyl-37,38,39,40,41,42-hexahydroxycalix(6)arene (1c) reveals that the former can be recognised by the latter at low concentrations (5*10-4 M - 3.72*10-3 M).

Methylene blue sensitized photooxygenation of 2-aminonaphthalene

Chawla, H M,Kaul, Kamini,Meena

, p. 733 - 737 (2007/10/02)

Methylene blue sensitized photooxygenation of 1-hydroxy-, 2-hydroxy, 1-amino- and 2-amino-naphthalenes has been investigated. 1-Hydroxynaphthalene yields 1,4-naphthoquinone exclusively while 2-hydroxynaphthalene and 1-aminonaphthalene do not yield tangible products in appreciable yields. 2-Aminonaphthalene gives 2,6-naphthoquinone as the major product rather than the formation of an unsaturated tetraaldehyde (1) as reported earlier .A plausible mechanism involving the intermediacy of hydroperoxides has been suggested.
